IMPROVEMENT lN GUN-WORMS.

Specification forming part of Letters Patent No. 62,994, dated March 19, 1867.

useful Improvement in Gun-Wormers and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilledv in the art to make and use the same, reference being had to the accompanying drawings, forming part' of this specification, in which Figure 1 is a perspective view of my improved extension gun-wormer attached to a ramrod. Fig. 2 is a central longitudinal section, showing the worm-screw extended. Fig. 3 is a similar view, showing the worm-screw retracted.

Similar letters of reference indicate like parts.

This invention relates to an improvement in gun-wormers or the screw on a ramrod for extracting bullets or a wad from the barrel of a gun; and consists in so arranging the screw, in connection with a thimble or case fastened on the end of the ramrod, that it shall be drawn within the case or protruded therefrom, as may be required, by a screw or slide movement.

The ordinary gun-wormer is a fixed screw, covered by a separate cap screwed over it, which cap is taken off when the wormer is used, and is therefore liable to be lost, whereas my improved wormer is a movable screw, attached in such manner to the thimble or case on the ramrod that it is covered when retracted or drawn into the case, and no part of the device is a separate part or liable to be lost. The ramrod with the ordinary wormer also has the great disadvantage of being shortened when the cap-cover is taken off to use it, while by the extension of my improved 7 wormer, when it is used, the length of the ramrod is increased, rendering it more convenient to handle in drawing a wad or bullet from the barrel, and gaining solid wood in the gun-stockat the breech, where it is needed.

A represents a portion of a ramrod, upon the end of which is screwed or otherwise secured ametal case or thimble, 0, having a barrel long enough to contain a worm-screw, m, having a shaft, n. The shaft n is fitted to slide freely in the barrel of the case 0, and has in it a central longitudinal slot, through which passes a pin, 0, that is secured to the case 0, and prevents the worm-screw from turning in the case while the shaft n slides back and forth for the extension or retraction of the worm-screw m.

The worm-screw m works in a revolving nut, b, which is fitted on the end of the case 0. The point of the worm-screw may be extended beyond the revolving nut b when desired for use, as shown in Fig. 2, or screwed back into the case, which covers and protects it generally, as shown in Fig. 3-.

While I prefer the revolving screw-nut for extending and retracting the worn-screw, as described, my invention is not confined to this particular arrangement for effecting its extension and retraction, as the same move ment may be efi'ected without the revolving screw-nut by means of a slide fastened with a side catch or common bayonet-lock.

Having described my invention, I claim as new and desire to secure by Letters Pat ent.

The gun-wormer consisting of the thimble O, worm-screw m, and revolving nut 1), arranged in such a manner that the said screw shall be extended or retracted, substantially as described.
